Eaton LESRK7I fuse - UL Listed, 200 kAIC

The LESRK7I fuse is engineered for high inrush motor protection, with a 7 A rating and a 200 kAIC interrupt capacity that tolerates fault currents typical of plant startup surges. This design minimizes nuisance trips and protects motor windings, helping maintain line uptime in pumps, conveyors, fans, and other automation equipment. The 600 V rating aligns with standard industrial power networks, enabling straightforward integration into existing motor circuits. Designed for use with conventional protective schemes, it pairs well with contactors and soft-start configurations to improve coordination and reduce unnecessary disconnections. Compact form factor and installation ease drive faster panel upgrades. At 5 inches long with a 0.81 by 0.81 inch cross-section and standard packaging, the LESRK7I fits tight control panels and standard fuse holders. The 1.6-pound weight simplifies replacements during routine maintenance, while consistent dimensions support clean, repeatable installations in control cabinets and motor starters. The fuse remains compatible with Eaton Edison protective architectures, helping sourcing teams streamline stocking and replacements across sites. Certifications and compliance provide clear regulatory validation. UL Listed and CSA Certified marks help satisfy safety audits and supplier qualification programs in North America. These certifications support project commissioning, NEC/cable-installation requirements, and ongoing maintenance discipline. While the product notes Not Applicable compliance in some regions, the United States approvals ensure robust protection for most industrial motor circuits. Non-indicating fuse indicator reduces field maintenance points and potential false signals. When status feedback is needed, engineers can rely on external indicators or remote monitoring to confirm operation without adding failure-prone built‑in lamps. This approach simplifies diagnostics, supports predictive maintenance, and lowers lifecycle costs in busy automation lines. In practice, technicians appreciate the simple, robust status behavior during routine checks. From a lifecycle perspective, standard packaging and readiness across Eaton’s catalog streamline procurement and stock planning. The rugged 200 kAIC interrupt rating and 7 A rating support a broad range of motor applications while minimizing spare parts variety. The LESRK7I also benefits from accessible datasheets, catalogs, and training videos that speed engineering validation and commissioning. Overall, deployments typically deliver reduced downtime, improved equipment uptime, and lower total cost of ownership in automated facilities.
